Misfires On all Cylinders - Help

[cruzanrs6]

Timing will jump a lot from 0 to positive numbers, that's tq reserves working.
Check VCDS blocks 91-92-93 for cam tensioners. I don't buy the "both broke at once" theory.
Take a look at "idle" reading, then rev her up and take a look at VCDS again.

Also, your cylinders with highest misfire count are on opposite sides of the engine. Can it be, that one of the tensioners failed and caused general AFRs to shift so much that the whole engine is suffering? Doesn't sound likely, there are 2 separate lambda control loops "per bank"...
Can also take a look at lambda control with VCDS, to see how much AFR adjustment you're getting.

Do you know off the top the measuring blocks for the fuel trim (lambda) on the RS6 ?

Thanks

001 shows it in the rightmost 2 windows.
As suggested by Mark, can also try unplugging MAFs. Will make the car run on "limp home" fueling & mostly eliminate up-throttle leaks contribution to the issue. See if that makes it idle okay-ish.
